The average distal curvature () of 48 LAD arteries is quantified from CCTA images.
Low values of in the LAD are strongly correlated with the presence of stenosis.
Classification of arterial health status using Kd is faceable.
Using a cut-off value of = 0.0537 mm−1 yields accuracy and AUC of 75%.
The could be an indication of a geometric risk factor for CAD.
